Using a .vrt - Cant load the geotiffs

[sweco-sekrsv]

When running from a vrt file I get errors like:
ERROR 4: merged_9_3_cog.tif: No such file or directory

The vrt file and the geotiff files are in the same directory under ctod\ctod\files
See screenshot below. Any ideas?

Here is my vrt file:

I changed the relative paths to absolute paths instead. It works:

I changed this:
<SourceFilename relativeToVRT="1">merged_9_2_cog.tif</SourceFilename>
to this:
<SourceFilename relativeToVRT="0">C:\Users\lmadmin\Documents\GitHub\ctod\ctod\files\merged_9_2_cog.tif</SourceFilename>

You can close the issue but an improvement would be to support relative paths as well!
